Companies like Netuitive and Prelert offer similar monitoring services powered by predictive analytics. But Vertila isn't just software-as-a-service, it's a full IT service with dedicated staff available 24x7.

Virtela's IT infrastructure management service also includes compliance auditing, network discovery and inventory management and network modeling. Some of its existing customers include FedEx, Google and RedHat.

Instead of calculating downtime using the average amount of downtime across all instances, Virtela is offering a service level agreement based on per-incident downtime. This means that any outage counts against its SLA, even if other incidents were resolved quickly.

We covered Netuitive and its predictive analytics system last year.
